Molecular Sophe: An Integrated Approach to the Structural Characterization of Metalloproteins: The Nysis of their high-resolution EPR spectra. Molecular Sophe involves the computer simulation of continuous-wave and orientation-selective pulsed EPR and electron nuclear double resonance (ENDOR) spectra. As aids to the correct analysis of these spectra, calculation of energy level diagrams, transitio

Spin-Hamiltonian Parameters from First Principle Calculations: Theory and Applicationstication [1]. The SH parameters are the principal outcome of an EPR experiment and represent a concise summary of the information content of the experiments. However, the power of the SH approach extends far beyond summarizing experimental results. The SH describes the physics of spin systems so we

EPR Studies of the Chemical Dynamics of NO and Hemoglobin Interactionsdiscovered by Furchgott [1]. Since then, the scope of the field has dramatically expanded to view the NO moiety as a ubiquitous signaling agent [2] that can modulate effector function through a variety of chemistries, most prevalently reactions with oxygen, thiols, and metal centers [3]. The seminal

A third small ligand X is situated in the bridge between Ni and Fe. In the catalytic cycle the enzyme passes through a number of redox states, several of wh

Unique Spectroscopic Features and Electronic Structures of Copper Proteins: Relation to Reactivityo-/four-electron reduction of dioxygen, and two-electron reduction of nitrous oxide. Traditionally, copper sites have been classified into three types based on their EPR features: the type 1 “blue,” the type 2 “normal,” and the type 3 “coupled binuclear” sites. However, more recent discoveries of th

Insulin-Enhancing Vanadium Pharmaceuticals: The Role of Electron Paramagnetic Resonance Methods in tes and spin-labeled or metal-substituted systems. Vanadium compounds have been shown to possess potent antidiabetic properties such as normalization of blood glucose levels and lipid metabolism. Vanadium compounds, and in particular vanadyl (V.O.) coordination complexes, represent a potential new tr

Chromium in Cancer and Dietary Supplementst recent evidence suggests that both these types of activities arise from varying amounts of Cr(VI) and reactive intermediates, such as Cr(V) species, which can be formed in vivo either by reduction of Cr(VI) or by oxidation of Cr(III) complexes. Applications of EPR spectroscopy for the studies of C

High-Frequency EPR and ENDOR Characterization of MRI Contrast Agentstter understanding of the mechanism of action of these contrast agents, and this in turn has aided the design of more potent nuclear relaxation agents. This chapter first takes a broad overview of MRI contrast agents and the need for EPR studies. High-frequency EPR studies of gadolinium contrast age
